I think I have a good question for the group
I am making a bunch of 3/4 thick parts out of oak and pine. They are various shapes, anything from a 3" dia. circle to 16" circle, 3" sqaure, to a
12"x18" rectangle. All these parts when done need to have a .05 wide slot around the perimeter, centered in the width. The slot must be a minimum of 1/2" deep. I work in a machine shop, so I purchased a .05 wide metal cutting slitting saw that is 3" in dia. I also got a bearing that had a 2" o.d. I then made an arbor to fit into my PC router, that mounts the bearing right above the slitting saw. My problem is, when I use it I think the router is going way to fast for the slitting saw, because it turned blue from the heat. It cuts the slot, but I don't think it's going to last through a whole lot of them. My next try was to get the thinnest 10" saw blade that I could get for my table saw. I then made and extension for my fence and stood the part on edge and spun it through the saw blade. This worked also, but it seems a little dangerous, if the wood would ever decide to take off. I really wouldn't mind doing it this way, but when I checked the slot width it is about .015 to wide. I mic'd the blade and found it was .065 across the teeth. My question is, does anyone have any better ideas how to put this slot in the parts. Or do you know where I can buy a really thin 10" saw blade?Thanks for any help Bob
